King James Version (KJV)

Hebrews 5:4

“And no man taketh this honour unto himself, but he that is called of God, as [was] Aaron.”

Verse in context — Hebrews 5

Who can have compassion on the ignorant, and on them that are out of the way; for that he himself also is compassed with infirmity.

And by reason hereof he ought, as for the people, so also for himself, to offer for sins.

And no man taketh this honour unto himself, but he that is called of God, as [was] Aaron.

So also Christ glorified not himself to be made an high priest; but he that said unto him, Thou art my Son, to day have I begotten thee.

As he saith also in another [place], Thou [art] a priest for ever after the order of Melchisedec.

Jesus as the ultimate High Priest and fulfillment of the Old Covenant.
